Hmm, there is one thing which I forgot to mention -
the double-TAB problem:

In [1]: import scipy

In [2]: scipy.in
scipy.index_exp        scipy.info             scipy.inspect
scipy.index_tricks     scipy.info_scipy_base  scipy.integrate
scipy.indices          scipy.innerproduct     scipy.interpolate
scipy.inf              scipy.insert           scipy.invert

In [2]: scipy.int
scipy.integrate    scipy.interpolate

In [2]: scipy.integrate.o
scipy.integrate.ode      scipy.integrate.odeint   scipy.integrate.odepack

In [2]: scipy.integrate.o

--> Here one has to press TAB twice to get the list.

I don't know if there is a work-around.
Somehow I think it is a minor inconvenience, but it might
be confusing to new-comers.

If there was a way to bind (e.g.) CTRL-P (or whatever character)
to toggling this, that would be great.
(So before pasting CTRL-P and after that back to the auto-indent mode.
But, as far as I know, there is no way to do that
binding via readline (please correct me - readline gurus!).

Somehow I thought I had it on my wish-list, suggesting that
it is not implemented (saying something like this normally
invokes your time-machine and maybe that's what just happened here,
who will be able to tell?;-)

I think it is a good default (apart from pasting thing ;-)
